redim preserve numarray(size) numarray(ubound(numarray)) = newobject size += 1

I've tried using the Register property of a deployment project, it works fine for COM components, but for Assemblies, I've tried vsdraCOM and vsdraCOMRelativePath, neither seems to do anything. No tlb file is generated, and no entry in OleView. I've tried registering through Custom Action, but the problem is in Uninstall, you can't use custom action because the dll's are deleted before any custom action is run which could unregasm. Has anyone dealt w/installing assemblies needing to be regasmed?
